Recording
Frequency the rate of an an electrical signal, or a vibrating mass that repeats within a cycle of (+) and ( ) amplitude; the measurement of the number of occurrences of a repeated event per unit of time. The frequency f is equal to the speed v of the wave divided by the wavelength λ (lambda) of the wave: f = v/Y
Amplitude The amplitude of sound waves and audio signals (also referred to as Volume) conventionally refers to the amplitude of the air pressure in the wave.
Wavelength The wavelength is the distance between repeating units of a wave pattern. It is commonly designated by the Greek letter lambda (λ).
Velocity travels through air at 68F is approximately 1130 feet per second or 34 meters per second. The speed is temp. dependant. Increases 1.1 ft/sec for 1 degree F.
Phase a measurement of a waveform, variations measured in degrees can be described as a time delay bt 2 or more wave forms.
Timbre is the quality of a musical note or sound that distinguishes different types of sound production or musical instruments. (Like hey, that’s a piano)
Decibels How intense or loud; The decibel (dB) is used to measure sound level, but it is also widely used in electronics, signals and communication. The dB is a logarithmic unit used to describe a ratio. The ratio may be power, sound pressure, voltage or intensity or several other things
Speed of Sound - the speed of sound in air is 344 m/s (769 mph or 1238 km/h).

Current the flow (movement) of electric charge. The SI unit of electric current is the ampere (A), which is equal to a flow of one coulomb of charge per second.

Impedance The opposition to the flow of alternating current in a circuit. Represented by the letter "Z" and measured in ohms, impedance is the combination of resistance, inductance and capacitance of the circuit.
